Any survival based Echii manga that is completed????

Also it would be better if the manga has less chapters.

@JinMori2000 I can think of Saikin Kono Sekai wa Watashi Dake no Mono ni Narimashita. I'm not a fan of ecchi and it was really strong in this one, so I dropped it, but it has an interesting plotline and it's completed. Each chapter is barely 10 pages, so don't let the chapter count deter you too.

I think you will like this one. It's pretty intense too aside from echhi
